As I see it, the consideration needed is that any file is going to "data/content dependent", therefore the idea of simulated/estimation for SMS compression would be questionable, that is without actually processing the file -- the method used with clients we support is to perform a BEFORE / AFTER with several data-samples. Also, the compression-method would also be a factor in terms of compression-result efficiency.
